What is Wireshark? Wireshark is open-source software for Windows and UNIX/Linux, open-source meaning that anyone can download it for free and can alter the source code however they please if they want to. It's considered the best network packet analyzer you can use today. But, What is a network packet analyzer? A network packet analyzer captures network packets on a specified network and displays very detailed data about the network protocols of each packet. Typical users are: Network administrators - who can use it to troubleshoot network issues Cyber Security Engineers - Can watch and see any attempted attacks on a network Developers - to Debug protocols For more information check out https://www.wireshark.org/ Check out our post on display filters and capture filters
